No Fault Code Displayed: Controller failure or NTC short

This will appear as if the washing machine is completely dead and lifeless with no indication of power at all as well as completely unresponsive but mains power is being supplied to the machine.

Check mains power supply (you did that, right?)

Check mains fuse in plug

Check NTC for short circuit

Check NTC wiring for shorts

If NTC tests okay replace control unit

N/C

No Fault Code Displayed: Door lock failure

Should the controller be unable to lock the door within 20 seconds of the program being started then the machine will revert to program selection. The start/pause LED will be seen to flash.

Check for mechanical issues with the door lock, door handle and door

Check door is fully closed

Check door lock

F01

Not filling with water or fill detection error

After six minutes, if the machine does not fill with water, then the water valves will be shut off and the LED with a water tap symbol will be lit.

You can attempt to restart the program by simply pressing the start/pause button again however, the washing machine will only work if the fill issue is resolved.

No Water In Your Washing Machine:

Check that the water supply to the washing machine is okay and there is water

Check for kinks in the fill hoses to the washing machine

Check inlet valve filters where fitted, ensure that these are clear

Check water inlet valves

Water In Your Machine But No Fill Error:

Check pressure switch hose for holes or blockage

Ensure that the washing machine is not siphoning back to waste water outlet

Check wiring to water fill valves, pressure sensor and control unit

Check all hoses for leaks

Check main control unit

F02

Aquastop error detected

If the Aquastop leak detection system is activated then the washing machine will drain for three to six minutes then the program will end and the door will unlock.

The activation occurs when the contact switch in the base of the washing machine inside is closed for more than 30 seconds.

No Water In Your Washing Machine:

Check that there is no water in the base of the washing machine

Check for any leaks from hoses

Check for leaks from the tub unit

Water In Your Machine But you have The Aquastop Error:

Check the Aquastop switch for a short circuit

Check the wiring to the Aquastop switch

Check control unit operation and also see error F26, pump triac short

F03

Water drain timeout error

This error is displayed when the washing machine fails to drain or, fails to drain in a predetermined time period. Once the allotted time is exceeded the machine will light the “Clean Filter” indicator.

The washing machine will time out on drain after approximately four minutes when it will switch to what is known as impulse draining where the pump will run for ten seconds, then off for ten seconds for a period of around four minutes in an attempt to clear any blockage.

Check drain pump filter on the washing machine for any blockages

Check the drain hose for any kinks or blockage

Ensure the drain pump is running

Check drain pump

Check for excessive foam as this can cause this error, see also code F18

F04

Water heating phase timeout

Should the water temperature not exceed 35˚C (on appropriate cycle or settings) after approximately fifty minutes the controller will display this error.

Check the water heating element for continuity

Check NTC for short circuit

Check NTC wiring for shorts

Check operation of NTC as this error can occur where the resistance does not alter

Check control unit

F05

Water temperature sensor error

Should the resistance reading for the NTC or thermistor fall out of the expected range then this error will be displayed.

Note that, as above, should the NTC be short circuited it can cause the washing machine to fail to power up, it will appear as if the washing machine is dead.

Check NTC for short circuit

Check NTC wiring for shorts

If NTC and wiring tests okay replace control unit

F06

Drive motor tachometer error

This error occurs when the main control unit fails to detect the motor speed from the tachometeric generator fitted to the motor either through an incorrect resistance or the tacho is not correctly fitted into place. The machine will try to detect the reading several times before aborting the program ans shutting down with this error being displayed.

When checking ensure that the drive belt and belt tension are okay as this can cause this error.

Check tacho resistance

check tacho placement

Check wiring for shorts

Check wiring harness connections between motor and main controller

Check drive belt for damage and tension

F07

Motor controller triac error

The main control unit has detected a short in the motor triac.

Check Motor for any signs of damage

Check main control unit by running test program

Whirlpool advise that if failure occurs with universal motor, replace control unit but if the washing machine has a CIM, BPM or Direct Drive motor to change the motor.

F08

Open circuit error detected on heating circuit

The main control unit in the washing machine has detected that there is an open circuit somewhere in the heating circuit.

The main control unit will detect this error at the start of a program and during the spin phase.

Check wash heating element for continuity

Check the wash heater for earth leakage

Check wiring to the heater

Check the control unit

F09

Motor control unit low voltage detected

This will fault code only be displayed on washing machines that have a CIM, BPM or Direct Drive motor fitted and an external motor control unit is used.

The motor control unit has detected that the voltage supplied to it is less than 170V AC and this is not a defect of the component itself but of the mains voltage input.

Check mains electrical supply to the washing machine as it is faulty

F10

Motor control unit detects an overheat

This fault code is only displayed on washing machines that have a CIM, BPM or Direct Drive motor fitted and an external motor control unit is used.

The motor control unit has detected an overheat situation.

Check the drum for any blockage, laundry can stop drum rotation if trapped

Check drum for noise or friction that may indicate a bearing failure

Check that the washing machine was not overloaded, this can cause this error

Check ambient room temperature, if too warm it can cause this error

In all the above cases allowing the machine to cool off with the issue resolved should allow the washing machine to work again. If the fault persists after these issues are addressed then the following will apply:

Check the motor for any defects, see fault code F06

Check the motor control unit for defects or fault

F11

Motor control unit has failed to initialise

This fault code will again only be displayed on washing machines that have a CIM, BPM or Direct Drive motor fitted and an external motor control unit is used.

The motor control unit has failed to initialise during the power on self test process or an error has been detected with the motor control unit. This can be cause by a wiring fault or short as well as loose plugs or poor connection.

When you power on the washing machine and voltage is supplied to the motor control unit it performs a self test sequence automatically. You will hear an audible “click” as the relay switches when power is applied and the self test is completed successfully.

Check harness between the motor control unit and main control unit

Check all connectors

Check motor for any fault, see fault code F06

F12

Heater circuit failure

This error code is displayed when the main control unit detects an error somewhere on the heating circuit, usually a short circuit in this case.

Check water heating element for continuity

Check water heater for earth leakage

check heater resistance

Check all wiring and connectors to the heater and from there to the main controller

Check main control unit

F13

Controller fails to detect door lock triac correctly

This error code is displayed if the main control unit fails to detect the door lock triac correctly. Also, if the controller cannot unlock the door after 240 seconds after the cycle is completed then this error will be shown.

If displayed switch the washing machine off completely, we recommend disconnecting it from the mains supply for a few seconds. Switch it back on and the controller will attempt to unlock the door once more but, if it fails to do so in the same 240 seconds the error code will be displayed once more.

Check all wiring and connectors between the main controller and the door lock

Check main control unit, probably requires to be replaced

F14

EEEPROM error

The main controller gets all its instructions from an EEPROM that is fitted onboard the main controller PCB, if there is an error reading this software then you will see this error appear.

It is worth noting that this is uncommon and to damage the EEPROM permanently as it is hard coded. We often comment that two things can alter a washing machine’s program software, physical damage to the chip or board and an electro-magnetic pulse, which is highly unlikely. These software instructions are designed to remain unchanged and cannot be altered without some form of interference normally. In other words, the problem has been caused by something outside of the washing machine.

On this range of Whirlpool washing machines the error can be show as a result of a mains power glitch, usually a power spike.

You can attempt to reset the washing machine by removing power for a short period and then reconnecting, it may clear the error.

Should that fail to work Whirlpool recommend that the test program is run to check the EEPROM, if this fails then you must replace the main electronic control board.

Run test program

Check control unit

F15

Drum Up circuit missing

This error code will only apply to Whirlpool top-loading washing machines that are fitted with the Drum Up circuit.

The main control unit has detected that the Drum Up switch is closing during the wash process.

This error code should only be displayed when running a test program.

Check the positioning of the electromagnetic device on the drum

Check the reed sensors position

Check the resistance of the reed sensor

Check the wiring and all connections between the reed sensor andf the controller

F18
FoD

Excessive foam detected during wash cycke

If the main electronic control unit is unable to detect that water has been drained out of the washing machine or unable to spin after several attempts then this fault code will be displayed.

The presence of excessive foam can cause the pressure sensor to be held open, tricking the electronics into thinking that the washer has failed to drain when water has in fact been emptied from the machine. Often, when left for a while to allow the lather to dissipate, the washing machine will work normally after a few hours.

Excessive lather can also cause spin errors as well as leaks.

Poor quality detergents and conditioners do have a tendency to foam or lather more than leading brands in our experience.

In virtually all cases, other then where there is an obvious fault, this will be a use related issue.

Customer is overdosing detergent and/or conditioner – Advise on use

Check detergent being used is suitable for automatic washing machines

Check that concentrated elements are not being used excessively

Check drain pump for any blockage or foreign objects

Check operation of the drain pump

Check operation of the pressure sensor or switch

Check that the machine is not siphoning to the drain

F19
F20

Control relay for motor controller faulty

This fault code is only displayed on washing machines that have a CIM, BPM or Direct Drive motor fitted and an external motor control unit is used.

The main electronic control unit has failed to detect the relay that switches the motor control unit on and off has operated correctly. This relay is fitted on the main electronic controller and it is highly unlikely that there is an issue with the electronic board that controls the drive motor.

Check wiring and all connectors between the motor and main electronic control units

Replace main electronic control unit

F21

User interface error

This fault code will only be seen on washing machine models that Whirlpool say have a Smart User Interface.

Essentially it is the main electronic control unit reporting that it can’t talk to the user board for some reason. The error should be displayed using the status LED because the control unit canot contact the user board to display it there.

Check all wiring and connectors between the main electronic control unit and user board

Check display module (most likely sue to damage or spillage etc)

Check main control unit

F22

Motor control unit communications failure

This fault code is again only displayed on washing machines that have a CIM, BPM or Direct Drive motor fitted and an external motor control unit is used.

The main electronic controller ha failed to communicate with the electronic motor control unit.

Check wiring between motor control unit and main electronic controller

Check all connectors are secure and connections are good

Check motor control unit functions

Check main control unit

F23

Pressure switch failure

Should the main electronic control unit detect that the wash level contact (or level) is on and the switch level for wash heater safety is off for any more than ten seconds during a wash this error code will be displayed.

Resetting the program may clear this error but unlikely.

Check the pressure switch or sensor for operation and electrically

Check the wiring from the main electronic control card to the level sensor

Check all connectors between the main controller and pressure switch

Run test program

Also see F08 and F12 as heater failure can cause this error to occur

F24

Water overflow detected

As with many washing machines the Whirlpool washers using this software have an overflow sensor built into the level switch or sensor, sometimes called a pressure switch. This is a safety measure to prevent flooding but it can be activated for a number of other reasons and, most commonly, by user error.

When activated the machine will close the water inlet valves if they are open and switch the drain pump on. The overflow level must have been reached for more than five seconds for these events to happen.

Once again, overdosing of detergents or conditioner can cause this error to manifest as excess lather or foam can travel up into the pressure sensor causing the level to be falsely reported to the electronics. Poor quality detergents also tend to foam more than leading brands.

Check detergent quality and dose

Check water outlet or drain hose for kinks or any blockage

Check drain pump filter for foreign objects and/or blockages

Check drain pump

Check that the water inlet valve is closing correctly

Check pressure switch for operation

Check pressure switch wiring and connectors

Check harness and connectors from the pressure switch to the main controller

F26

Drain pump triac failure

This error code is displayed when the main electronic controller fails to detect the triac that controls the outlet drain pump during the wash cycle.

Check pressure switch contacts and connectors

Failure of the pressure switch or level sensor can also give rise to this fault code

Run test program

If failure persists after test and verification of pressure switch, replace main controller

F27

Reverse relay failure

This fault code will only be shown when the test cycle is in operation.

The electronic controller has detected that the main drive motor can only run in one direction.

Check the motor field windings

Check the motor connectors

Check harness and connectors between main controller and motor

Check main electronic controller operation

F28

Tapped field failure

The electronic controller has been unable to switch on the tapped field on the drive motor.

Check that the correct motor is fitted if this has been replaced

Check the motor field windings

Check the motor connectors

Check harness and connectors between main controller and motor

If all the above is okay replacing the main controller is advised by Whirlpool

F29
FdL

Door cannot unlock – mechanical issue

This error code indicates that the washing machine cannot unlock or release the door lock for some reason and, in this instance, this will be due to a mechanical issue in most cases.

Check door for mechanical problems

Check door hook, latch or catch for issues

Check door safety interlock

Check wiring from door lock to electronic controller

Wave Washing Machines

On Wave series Whirlpool washing machines the door lock will time out to fail in four minutes however if the error is detected three times in sixteen cycles this error will occur on the third instance of the problem being detected.

The cycle can be restarted but the door will remain locked.

The indication of this problem can only be cleared by running the test program or by reprogramming the electronic card

Wave 2 Washing Machines

As above but:

The door lock time out is increased to six minutes.

The door lock is not locked whilst the failure is displayed.

It is not required to delete the failure as above.

F31
bdd

Blocked drum detected

This error code is only used on Whirlpool top loading washing machines.

Although almost all washing machine manufacturers refer to this as a “blocked drum fault” what they mean in layman’s terms is that the drum in the washing machine is jammed and cannot move.

In this instance, because it is used on a top-loader, it can mean as follows but also see error code F06 for other possible causes.

Check that the drum door is closed properly

Check that the belt is positioned correctly

Check for trapped items

F40

Communication failure or low ambient temperature

This fault code will only be shown when the test cycle is in operation.

The main electronic controller fails to be able to communicate with the Myst Extension Board (MEB).

It is possible that this code is also displayed in the ambient (room) temperature is lower than 5˚C where the washing machine is positioned although it has been reported to occur where the temperature is a little higher than this therefore, greater than 10˚C should be regarded as a minimum ambient temperature.

Check that the ambient room temperature meets requirements

Check for power at CU2 on the MEB

Check that the communication cable is secure to the user interface board

If the code is displayed at the start of a test cycle:

Run drain cycle and allow this to fully complete to reset

Restart test program

If all above is okay, replace the MEB

F41

MEB board failure

This fault code will only be shown when the test cycle is in operation.

The MEB has been detected as being faulty.

Check for power on CU2 on the MEB

If no power, replace MEB

F42

Stem unit failure

This fault code will only be shown when the test cycle is in operation.

If there is any failure detected in the steam generating unit or the control NTC for the steamer then this error code will be displayed on the test program.

SAFETY NOTE: Before working on the steam unit ensure that the washing machine is disconnected from the mains!

Check the wiring harness between the steam unit, NTC and MEB

Check all fuses and/or resettable thermostat are not open circuit

Check the resistance of the steamer (see below)

Check the NTC is not open or shorted

Check all hoses are connected

Check that the steamer tube is not blocked

Check water heater NTC (see F04 and F05)

If all above is okay, replace steamer

To check the steamer resistance measure across pins one and three, you should get a reading of 48-57 Ohms (Ω), if it is outside of this reading then it is likely faulty.

F43

Steam valve failure detected

This fault code will only be shown when the test cycle is in operation.

If there is no water supply or a restricted supply from the likes of a low mains water pressure then this error code will be shown.
